Yep, nice stuff: linux-log-summary does nicely summarize it all like
this here:
...
include/linux/kernel.h:120:19: warning: cast from function call of type ‘void *’ to non-matching type ‘long unsigned int’ [-Wbad-function-cast]: 40 warnings in 1 logs
include/linux/kernel.h:67:27: warning: conversion to ‘int’ from ‘long unsigned int’ may alter its value [-Wconversion]: 2 warnings in 1 logs
include/linux/kernel.h:67:33: warning: conversion to ‘long unsigned int’ from ‘int’ may change the sign of the result [-Wsign-conversion]: 3 warnings in 1 logs
...
which I ran on a file built with W=123.
So I'd say everything needed is there to massage those build logs.
Thanks.
